Non-EGR equipped diesels – extend drain intervals up to two times (2X) the OEM^ recommended drain interval or one year, whichever comes first, or longer based on oil analysis.

^OEM = Original Equipment Manufacturer

Modifications and Alterations – Engines operating under modified conditions are excluded from extended drain recommendations. Examples include the use of performance computer chips; non-OEM approved exhaust, fuel or air induction systems and the use of fuels other than those recommended for normal operation by the manufacturer.
Mechanically sound engines are in good working condition and do not, for example, leak oil or consume excessive amounts, are not worn out, do not overheat, do not leak anti-freeze and have properly working emission control systems. AMSOIL recommends repairing malfunctioning engines prior to the installation of AMSOIL synthetic oils.
Personal vehicles frequently traveling greater than 10 miles (16km) at a time and not operating under severe service.
Gasoline Engine Severe Service defined as turbo/supercharged engines, commercial or fleet vehicles, excessive engine idling, first and subsequent use of AMSOIL engine oil in vehicles with over 100,000 miles, daily short trip driving less than 10 miles (16 km), frequent towing, plowing, hauling or dusty condition driving.

Diesel Engine Severe Service defined as extensive engine idling, daily short trip driving less than 10 miles (16 km), frequent towing, plowing, hauling or dusty condition driving.

For maximum engine protection, use only AMSOIL high efficiency oil and air filters, which offer, not only incredible contaminant removal ability, but also long change interval capability for maximum economy.

Note: Most quick lube service centers will install these products upon request or you can install them yourself.

Unfortunately, in order to make it simpler for the majority of our website visitors (who are searching for AMSOIL and other lubrication and filtration information with Javascript turned on) to find the synthetic lubricants data they seek, a javascript based site was really the most effective solution.
